ATTACHMENT FOR GRAiN-BINDERS.

Specification of Letters Patent.

Patented. March 6, 1906.

Application filed August 5, 1905. Serial No. 272,912.

To all whom in many concern:

Be it known that I, SHEPHERD W. BERRY, a citizen of the United States, residing at Lawrence, in the county of Douglas and State of Kansas, have invented certain new and useful Improvements in Attachments for Grain- Binders, of which the following is a specification.

This invention relates to certain improvements in attachments for breastplates of cord-binding harvesters, the purpose of the invention bein to provide means whereby the straw will be prevented from being carried by the needle through the slot in the breastplate and to the knotter mechanism; and my invention consists in providing the breastplate of a grain-binder with a spring that is constructed to provide a pair of springarms that are maintained below the slot of the breastplate, so that the resilient arms may be engaged and separated by the needle to wipe such needle prior to its assa e through the breastplate, and thus ee t e needle of any straw that may be carried thereby, so that there will be no liability of straws being interwoven with the knot, as is frequentl the case. i

In t e drawings, Figure 1 is a view showing my invention applied to a grain-binder of ordinary construction, such view illustrating the arts adjacent to the breastplate by whic the needle-clearing spring is carried. Fig. 2 is a bottom plan view of one form of breaslplate with the clearingsprin attache and Figs.3 and 4 are views of ifferout forms or shapes of the needle-clearin spring, Fig. 3 showing the form of s ring use with the Plano self-binder and 4 that used with the Deering binder. v

Reierrin to the drawings, Fig. 1, A is the binding ta 1e or deck; B, the breastpiate, having therethrough a longitudinal slot, and to such breastplate the standard for the knotter-shaft is usuall secured. The needle C is mounted on a shafl C. The above-mentioned parts bein of ordinary construction will be readily un erstood by those skilled in the art.

The breastplates will vary as to sha different types of machines, and in appl my invention the shape of the spring wi be varied to conform with the sha e of the breastplate adjacent to the slot t erethrough, as well as to the shape of the art that engages the beam or so port for the f rward part of the breastplate or instance, with a breastplate e in g l as used with the Deering and with the Plano shaped as indicated by Fig. 3 of the drawings, and minor changes maybe made to adapt my invention to other types of self-binders. The needleclearing spring E is formed from a single piece of spring-wire and has side arms or members e e, and where the arms or members join there is formed an eye or coil f, through which one of the bolts that also connect the breastplate to its so port may be used to hold the spring E in p ace. Instead of an eye f a loop f may be formed, the open end of the loop being closed by a bandf, the ends of such band being connected by a rivet If. The arms of the needle-clearing s ring ie parallel to each other and in line wit the slot through the breastplate except when spread by the needle In practice the needle 0 after passing through the deck A, upon which the grain is gathered, engages the inner sides of the arms or members e e, pressing the same a art, so that as the needle C passes between t e arms they will engage or wipe the needle, so as to remove therefrom any straw that may be entangled between the needle and the bindin twine, so that the arms will clear the need e and revent any straw being carried through the s ot in the breastplate to the knotter.

The flanges g g, (see Fig. 2,) that depend from the breastplate adjacent to the slot therethrough, will prevent the one-piece spring be ing turned sidewise upon the bolt and will limit the movement of the arms of the spring away from each other, and when a loop, as f is present the band f will prevent the 00p being spread when the attaching-boit is forced through such loop.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A cord-binding harvester having a needle and a slotted breastplate that is provided on its under side adjacent to the longitudinal edges of the slot with depending flanges and beyond the end of the slot with an aperture for the passage of a bolt, in combination with a needle-clearing spring that is mounted to partially overlie the slot throu h the breastplate, the spring having similar y-shaped side members and at one end an eye through which is passed a bolt that holds the spring between the depending flanges of the breastplate, substantially as shown.

2. The combination in a cord-binding harbinders the needleclearing spring will be vester,ofaneedle andalongitudinally-slotted In testimony whereof I have signed my breastplate through which the needle asses, name to this specification in the presence of a bifurcated spring attached to the reasttwo subscribin Witnesses.
